Voyno-Yasenetsky Scientific and Practical Center of Specialized Medical Care for Children, Moscow, Russian Federation Ivanovo State Medical Academy, Ivanovo, Russian Federation Purpose. To evaluate the effect of treatment with botulinum toxin type A on neurocognitive functions in children with strabismus. Material and methods. This study included 6 patients aged 4.5 to 7.7 years with various forms of strabismus before and after chemodenervation, observed for 6 months at V.F. VoynoYasenetsky Scientific and Practical Center of Specialized Medical Care for Children. All children underwent standard ophthalmological screening before and after chemodenervation. Intelligence was studied using the WPPSI-IV scale. Results. Based on the results obtained, we did not notice a decrease in the level of intelligence; we found an increase in the level of intelligence in 2 children (33.3%) by 1 point. In 3 children (50%) the level of intelligence did not change after chemodenervation. It was also found that 3 children (50%) had a high average IQ and 3 children (50%) had an average IQ. Conclusion. Results of this study demonstrate positive impact of chemodenervation on the cognitive functions of children with strabismus, observed by an ophthalmologist. Testing with the WPPSI-IV scale opens new horizons for identifying cognitive impairments in children. This example was used to demonstrate safety assessment of chemodenervation on neurocognitive functions in children. This technique allows if deviations are detected to provide timely correction of this condition, and helps reduce the risk of patient disability.
